The park currently maintains three main circuits for visitors and, with an early start, it's possible to visit the park on a day trip, but it is advisable to camp overnight. If you are interested in longer treks across the rainforest mountains, visit the MNP office in Fort Dauphin.
- Circuit Tsimelahy (3.7km, two to 2½ hours) The most popular route is an excellent trail in the bird-rich transition zone between the humid east-coast forest and the dry vegetation of the central region. There are campsites and some natural bathing pools. From Fort Dauphin, turn right at the signpost 48km along the RN13, then proceed 8km along a rough road. Check the security situation before setting out.
- Circuit Malio A bird- and amphibian-rich loop of 10km (four to five hours) through low-altitude humid forest with waterfalls and natural bathing pools that may be inaccessible during rainy season. From Fort Dauphin, turn right after 25km on the RN13, then proceed 13km on a dirt road (4WD advisable).
- Circuit Mangatsiaka A gentle loop of 4km (two hours) in bird-rich dry forest. From Fort Dauphin, follow the RN13 for 54km, then turn right and proceed 4km on a dirt road.
